Added support for sending hashes with Bukkit. 1.10 clients need the correct pack file sha1 hashes to accept the pack! Take a look at this post how to get them!
Fixed an issue under Bukkit when some values weren't configured in the config
Added support for the different logging level enums and weights in the debug option and made it so "debug: false" completely disables the debug logging instead of logging it with the FINE level
Added a permission to get notified when an update is available (forceresourcepacks.updatenotification)
